Abstract: An aneurysm occlusion device (10), a therapeutic apparatus for aneurysm occlusion and an aneurysm occlusion system. The aneurysm occlusion device (10) includes an expandable mesh structure (11) and a guide structure (12). The expandable mesh structure (11) has an expanded configuration, in which it assumes a spiral shape spiraling from a distal end (111) to a proximal end (112) thereof, and a collapsed configuration for its delivery into an aneurysm (30) from a blood vessel. At least a portion of the guide structure (12) is disposed in an inner cavity defined by the expandable mesh structure (11) and, when the expandable mesh structure (11) is in the spiral shape, expands into a spiral shape in the inner cavity of the expandable mesh structure (11).

Abstract: An end structure of a push rod for a guglielmi detachable coil, detachment systems thereof, and an embolization system are disclosed. The end structure includes at least one metal wire, at least one first conductive tube, at least one insulator and at least one second conductive tube. The at least one insulator is connected to both the first conductive tube and the second conductive tube and configured to electrically insulate the first conductive tube from the second conductive tube. One end of the at least one metal wire is electrically connected to the at least one second conductive tube. The first conductive tube and the second conductive tube are coaxially assembled into an integral structure, which can be inserted into an electrolytic device, resulting in the formation of an electrical circuit. In this way, operation to be performed by a physician can be simplified, and a coil can be detached within a short period of time, resulting in increased surgical efficiency.
